CAR-STARE.

Specication of Letters Patent. Application filed April 4, 1907. SerialNo. 366,342.

Patented July 9, 1907.

To rzZZ whom it may' concern:

Be it known that I, ROBERT E. FRAME, a citizen 'of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulhnprovement in Car-Stakes, of which the following is a full, clear, andexact description, such as Will enable others skilled in the artitowhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this speciiication, in which-AFigure l is aside elevation of a car stake constructed in accordancewith my invention; Fig. 2 is an edge view of the stake shown in Fig. l;and Fig. 3 is an en; largcd cross sectional :view of the stake.

This invention relates to car stakes.

The objectoi my invention isto provide a pressed metal car stake thatwill be strong and which will not' project a great distance beyond theside of the car on which it is used'.

The pressed metal car stakes which vhave heretofore been used to someextent were provided with a longitudinally extending. strengtheningrib'that projected outwardly some distance beyondthe body of the stake,thus adding considerably to the dimensions of the stake and accordinglynecessitating a reduction in width of the car body on which the stakeWas used so that the extreme width of the car would not be greater thanthe width of tunnels and other openings which are constructed to receivecars` of standard width.

Consequently, stakes of the lcharacter referred to have i0 not gone intogeneral use for two reasons; irst, because they could not be' used oncar bodies oi standard width as they projected too great a distancebeyond the sides ofthe car and prevented it from passingthrougliopenings of ordinary size, and second, because 5 theycould onlybe used on specially constructed car bodies, the carrying capacity ofwhich was much less than the car bodies oi` standard size.

My improved stake is so constructed that it can be used on standard sizecar bodies and moreover, 1t is much stronger than the pressed metalstakes which have heretofore been used and also possessesother desirablefeatures.v

Referring to the drawings which represent the preicrred form of myinvention, 1 designates the body por- 5 tion of a car stake formed from.pressed metal, said 'body portion bei-ng'app'roximately channel-shape incross section, and 2 designates a continuous flange that projectslaterally from the sidesand top and bottom of the body portion, thisiiange being provided with open ings'to receive the fastening deviceswhich secure the stake to the side of the car.

As shown in Fig. 2, the body portion 1 curves inwardly at 3 and mergesinto the flange at the lower end of the stake and from a point adjacentthe center of the stake, said body portion gradually diminishes in depthtowardthe upper end of the stake where it merges into the flange at thetop of the stake, thereby producing a stake which is closed at its upperand lower ends so that it will be impossible for moisture and dirt toget into the interior of the stake. Theouter wall of the body portion 1is provided with a longitudinally extending strengthening rib 4 thatprojects inwardly, thus forming two parallel ribs 5 closed at theiropposite ends and extending the'entire length of the stake. Asthe depthof the body portion of the stake does not exceed the depth or thicknessof the ordinary wooden stakes and stakes formed lfrom commerciallyrolled members I am able to use'the stake on'car bodies of standardsize. Furthermore, lthe stake is very strong and rigid as it is providedwith three' parallel ribs that' 70 extend throughout its entire length.

Having thus described-my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A pressed sheet metal car stake having an approximately channelshapedbody portion, the outer wall of 5 which is provided with an inwardlyprojecting strengthening rib; substantially as described.'

2. A car stake formed of pressed sheet'metal comprising a body portionof approximately channel shape in cross section provided in its outerwnll with an inwardly projecting strengthening rib extending throughoutthe major portion of.its length, and flanges on said body portion forsecuring the stake to the side ora car substantially as described.

3. A car stake formed of'pressed sheet metal and com prisingnvhollowbody portion, the outer wallof'which is 85 provldedrwith a plurality`ofparallel strengthening-ribs that extend throughout the major portionof the length-of the stake, and attaching flanges on said body portionsubstantially nsdescribed.

4. A car stake formed of pressed sheet metal and com- 9() prising a bodyportion of approximately channel-shape in cross section, said bodyportion merging at its opposite ends into flanges, the outer wall ofsaid body portion being provided withA an inwardly projecting rib, andintegral Vflanges at the sides of said body portion; substantially asdescribed.

5. A car stake formed of sheet metal and comprising a hollow bodyportion of varying depth, and a continuous integral flange projectinglaterally from the sides and top and bottom of said body portion,theouter wail of said lo() body portion being shaped to form a pluralityof parallel strengthening ribs that'diminish in depth gradually from thelower to the upper end of the stake; substantially as described.

. In testimony whereof- I hereunto aiiix my signature in the presence oftwo witnesses, this second day of April d 1907.
